1989 Other Mercedes Benz Models Mercedes 300ce

I have a Mercedes Benz 300CE, my problem started when driving sometimes it would just die, then I would wait a bit and fire it up again and it would drive well again. Now it just won't start at all.I know that there is a fuel supply cause when you loosen the fuel line there is a nice spray of fuel. Could anyone please help me as this is my only mode of transport.
